Columnea is agenus of around 200species ofepiphytic herbs and shrubs in the familyGesneriaceae, native to the tropics of theAmericas and theCaribbean. The tubular or oddly shaped flowers are usually large and brightly colored – usually red, yellow, or orange – sometimes resembling a fish in shape. A common name isflying goldfish plants (see also the relatedNematanthus) due to the unusual flower shape.

The genus was named byCarl Linnaeus after theLatinized spelling of the name of the 16th-century Italian botanistFabio Colonna (Latin:Fabius Columnus).[2][3]

Thesegregate genusBucinellina is considered by many botanists asynonym ofColumnea. A full list of the species now accepted in the genus, along with their synonyms, can be found at the World Checklist of Gesneriaceae.[4]

Cultivation

[edit]

Columnea species grow as epiphytic plants in the wild and require bright light, good air circulation, and a well-drained growing medium that is allowed to dry out slightly between waterings. They are very tolerant of underpotting and seem to bloom best when potbound. Most are tropical plants and are easy to grow under indoor or greenhouse conditions but some species come from high altitudes and require cooler temperatures to grow well or bloom. Many of the species are seasonal bloomers, buthybrids andcultivars can be more or less continuously blooming.

The hybridColumnea ×banksii has gained theRoyal Horticultural Society'sAward of Garden Merit.[5]
